Ex-intelligence agent James Ryker sets out on a revenge mission that takes him from the crystal waters of Mexico's Caribbean coast right back to his country of birth, England. Once there, he stumbles upon a terrorist attack targeting his old employers. All the clues point to The Silver Wolf. But just who is he, and why is he hell-bent on punishing not just Ryker but his closest allies?

Rule number one for an agent of the secretive JIA is to follow orders, no matter what. But James Ryker has never cared much for rules. He only wants to do what is right. Assigned to join a crew of elite security personnel in Chabon, Africa, Ryker’s mission objective is clouded by politics and obfuscation, and he knows only that to protect British interests in the region, he is to infiltrate the close protection team of the government of Chabon, a country with a dark and violent past.  

What do you do when the love of your life vanishes? Lisa was taken, and Ryker will find the perpetrator. Ryker, who is an ex-intelligence agent, is framed for the murder of a former informant and thrown into a jail run by The Black Hornet, the notorious leader of a drug cartel. What connects the cartel to the informant's murder and to Lisa's disappearance? Who can help in Ryker's hour of need?

He dedicated most of his life to the Joint Intelligence Agency. Now, James Ryker wants to start afresh. However, he soon hears about the murder of a woman whose fingerprints match those of a former adversary who's been missing, presumed dead...an assassin known as the Red Cobra. But Ryker confirms a case of mistaken identity. Who is the dead woman? And where is the real Red Cobra?

He's back and better than ever. James Ryker, a veteran intelligence agent now freelancer, working for the secretive Joint Intelligence Agency on an op-by-op basis, finds himself embroiled in a complicated mission that will test him to his limit. When a simple surveillance mission goes awry and the key target is kidnapped in broad daylight in a busy London square, Ryker knows he has his work cut out. Ryker is tasked with figuring out what went wrong. But when his good friend Sam Moreno disappears without a trace, the mission becomes more personal than he could have imagined. 

Everyone has a breaking point. Carl Logan might have just found his. The JIA sends intelligence agent Carl Logan on a routine mission to Russia. It should have been simple. But when Logan's cover is blown, he's transported into a world of hell he thought he would never see again. Something is different this time, though, and before long doubts begin to surface in Logan's mind as to why the assignment went so wrong. Logan has never been short of enemies.

Aydin Torkal - aka Sleeper 13 - is on the run. Hunted not only by the world's intelligence agencies but also by the elite brotherhood of insurgents he betrayed, he has lived the past year like a ghost. Until now. MI6 agent Rachel Cox knows Aydin better than anyone. The only person who believes he is an ally in the ongoing war on terror, not the enemy. So when a coded message arrives from him, warning her not to trust her own colleagues, Rachel must choose between her career and the truth. 

Against all odds, Aydin Torkal - aka Sleeper 13 - broke free from the terrorist group that took him as a child and raised him into a life of violence and hate. In the two years since, he's been tracking and killing all those responsible. But he's not done yet. Now living a secret life in London, he receives a surprise visit from Rachel Cox of MI6. She needs his help to infiltrate a sinister new terrorist cell who've taken root in the USA. Aydin is initially reluctant.

Carl Logan was the perfect agent. A loner with no real friends or family, he was trained to deal with any situation with cold efficiency, devoid of emotion. But Logan isn't the man he used to be or the asset he once was. Five months ago his life changed forever when he was captured, tortured and left for dead by Youssef Selim, one of the world's most violent terrorists. When Selim mysteriously reappears in Paris, linked to the kidnapping of America's attorney general, Logan smells his chance for revenge.

Smuggled to the Middle East as a child. Trained as one of the most elite insurgents of his generation. Forced to do things no one should, for a cause he couldn't believe in. But as his brothers were preparing to kill, he was looking for a way out. Now, on the eve of the deadliest coordinated attacks the world has ever seen, he'll finally get his chance. He will break free and hunt down those who made him a monster. He must draw on all his training to survive. He is Sleeper 13.

The case was closed. Now everyone connected is getting killed. Let the games begin....

He was last seen heading off with 17-year-old Sophie Blackwood, and a blood trail seems to show that Sophie has been kidnapped. DI Dani Stephens, still struggling after an attack by her serial killer brother, is thrown into a desperate search for a murderer who kills and keeps on killing.

Incarcerated in a prison hidden from society, an all but broken man has a terrifying secret. His captors know what he has done, have tortured it out of him, but they do not know everything. All he needs to do to bring down the Western world is hold out for long enough. Still reeling from a CIA double-cross, MI5 need their prisoner back. Alex King accepts a mission of unparalleled risk. But first, he must commit a crime that will see him treated outside the US legal system and get to a prisoner who can destroy or save mankind with the knowledge he holds. 

The most callous and resourceful woman imaginable has escaped the net. MI5 agent, Alex King shut down her venture, exposed her as a murderer and a criminal. And now she has the woman he loves. But King’s skills can prove invaluable. His enemy knows the workings of the Russian mafia, and now she has a man who can shut them down while she takes over their syndicates. King takes on the most ruthless men imaginable. But he discovers enough about his tormentor and her past to take the fight to her.

In the frozen wilds of Lapland, an isolated hotel becomes the only sanctuary from the most powerful Arctic storm in living memory. A Russian defector holds the key to a terrifying secret. Pursued by ruthless mercenaries, who will stop at nothing to silence them, the defector heads for the hotel, unaware that the man they mean to meet has been murdered. King must intercept the defector and get the deadly secrets they hold to safety. But whom can he trust? And why, after all these years, has King’s past finally caught up with him here? 

The agents from an MI5 mission against the CIA are being hunted and killed.
